CONDENSER.

Application filed March 17, 1921. Serial No. 453,021.

To all whom it may concern.

Beit known that-we, NORMAN W. KRAsn and VERNIE LEsEssNn GADDY, citizens of the United States, and residents of, respectively, Clarendon, county of Arlington, and State of Virginia,-and Dillon, county of D11- lon, and State of South Carolina, have invented an Improvement in a Condenser, of

which the following is a specification.

The subject of this invention is a condenserespecially adapted for the manufacture of solid compounds of ammonia and carbon dioxide with or Without water vapor, or solid condensates of other condensable gases and (or) vapors.

The main object of the invention is the provision of a condenser equipped with means for removing the solid condensate therefrom, as formed.

The invention also contemplates the provision of meansfor collecting the condensate when'removed.

A still further object of the invention is the provision of a simple, cheap and efficient condenser.

With these and other objects in view the invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the.

scope of what is claimed without departing from the spirit of the invention.

One. practical embodiment of the invention is illustrated in the accompanying drawings, wherein:

Fig. 1 is a view in vertical section, parts in elevation, of a condenser constructed in accordance with the invention;

Fig. 2 is a section taken on the lines 11-11 for the reception of members 2 and 3 of a Stufling box.

-A shaft 8 passes through the stuiiing box, in which it is rotatable, and has connected thereto at its lower end a blade 6 disposed Within the cylinder and formed with scraping members 6 along each longitudinal edge, which members are adapted to contact the walls of the cylinder 1 and remove therefrom the condensate formed thereon by the gases coming in contact with the cool Walls of the cylinder.

A. suitable means, such as the pulley 10, is secured to the upper end of the shaft 8 for the purpose of rotating the shaft and blade.

At the lower end of the blade 6 is secured a stub shaft 7 which is journaled in a cross bar 9 suitably fastened within the lower end of the cylinder.

, For the purpose of cooling the cylinder we may use a cylindrical jacket 5 which encircles the cylinder and is open at its upper end and secured to the cylinder at its lower end by an ordinary flange joint or clamp 4.

To permit of proper circulation of the cooling fluid an inlet pipe 18 is threaded into an aperture formed in the jacket adjacent its lower end and another pipe 19 is threaded into an aperture formed in the jacket adjacent its upper end.

A receptacle 11 is positioned below the open lower end of the cylinder 1 to receive the condensate scraped from the walls of the cylinder by the blade 6. This receptacle may conveniently be threaded into the lower flange of the flange joint 4 as shown most clearly in Fig. 1. To permit escape of gases from the condensate in the receptacle, an

outlet pipe 12 is provided which communi- .der 1 n communication with a gas mixer 13 in which gases may be mixed at any desired temperature before passing to the condenser.

The mixer is provided with an inlet pipe 13' if through which gas may be admitted thereto and is in communication with a saturator 15 through a pipe 16. The saturator has a gas inlet pipe 17 terminating near the bottom. thereof through which gas may be admitted tobubble through the liquid and pass to the mixer.

\s an example of theoper'ation of the device, the operation in carrying out the with ammonia which is admitted directlyto the mixers through the inlet pipe 13. The mixer is kept at a temperatureof about 80 C. or at such temperature as to prevent condensation.

The mixture of ammonia, carbon dioxide and water vapor then passes through pipe M to the condenser where it is condensed on the cool walls of the cylinder 1 from which it is scraped by the rotating blade 6 and falls into the receptacle 11, from which it is recovered.

By suitable manipulation and control of the rate of flow of ammonia and carbon dioxide and suitable regulation of the temperature of. the water in the saturator 15, various compounds formed from ammonia, carbon dioxide and water may be produced.

7 so Having described our invention what we claim as new and desire to secure by Letters Patent is:

1. A condenser, embodying a vertically disposed cylinder, means tor admitting fluid to the cylinder, a closure for the upper end of the cylinder a shaft journaled in the closure, a scraperblade secured at its upper end to the shaft and contacting the walls of the cylinder, a cross bar fastened in the lower end of the cylinder, a stub shaft secured to the lower end of the scraper blade and journaled in the cross bar, a cooling jacket surrounding the cylinder, a receptacle below the cylinder, and a clamp secured to the lower end of the cylinder and connectin the cooling jacket and receptacle to the cyhnder.

'2. A condenser, including a cylinder open at its lower. end, means for admitting fluid to the cylinder, a closure for the upper end of the cylinder, a shaft journaled in the closure, a scraper blade secured to the shaft and contacting the Walls of the cylinder, a cooling jacket surrounding the cylinder, a receptacle below the cylinder and a clamp secured to the cylinder and connecting the cooling jacket and receptacle to the cylinder.
